This circuit consists of two independent,high gain,
internally frequency compensated which were
designed specifically for automotive and industrial
control system. It operates from a single power sup-
ply over a wide range of voltages. The low power
supply drain is independentof the magnitude of the
power supply voltage.
Application areas include transducer amplifiers, dc
gain blocks and all the conventional op-amp circuits
which now can be more easily implementedin single
power supply systems. For example, these circuits
can be directly supplied with off the standard + 5V
which is used in logic systems and will easily provide
the required interface electronics without requiring
any additional power supply.
In the linear mode the input common-mode voltage
range includes ground and the output voltage can
also swing to ground, even though operated from
only a single power supply voltage.
